［産業上の利用分野］
この発明は芯材を金属被覆する方法に関するものであり
、たとえば光ファイバに金属被覆する方法に関するもの
である。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to a method of coating a core material with metal, for example, a method of coating an optical fiber with metal.
［従来の技術］
従来、光ファイバ等の芯材に金属被覆する方法として、
金属のテープで芯材を包み、その継目を溶接していくテ
ープ溶接法、有限長の金属管に芯材を通し、その金属管
を絞り加工するパイプ嵌合法、芯材のまわりに金属管を
押出し加工で形成し、被覆していく押出法等があった。[Prior Art] Conventionally, as a method of coating the core material of optical fiber with metal,
The tape welding method involves wrapping a core material in a metal tape and welding the joints; the pipe fitting method involves passing a core material through a finite length metal tube and then drawing the metal tube; and the pipe fitting method, which involves wrapping a metal tube around the core material. There was an extrusion method, etc. in which it was formed by extrusion processing and then coated.
［発明が解決しようとする課題］
ところが、テープ溶接法では溶接した継目にピンホール
が発生することがある。このため、このピンホールから
金属管内に外部雰囲気中のＨ２ＯやＨ２などが入り込み
、芯材を傷めてしまうことがあった。[Problems to be Solved by the Invention] However, in the tape welding method, pinholes may occur in welded seams. Therefore, H2O, H2, etc. in the external atmosphere may enter the metal tube through the pinhole and damage the core material.
また、パイプ嵌合法では金属管の長さに制限があるので
、金属管と金属管との継目に溶接を施す必要があった。Furthermore, in the pipe fitting method, there is a limit to the length of the metal tubes, so it was necessary to weld the joints between the metal tubes.
このため芯材が長くなると金属管に溶接した継目が多数
少じた。この溶接した継目は、前述の理由等により機密
性や機械的信頼性に劣ることがあった。For this reason, as the core material became longer, many of the joints welded to the metal tube became smaller. This welded joint sometimes has poor airtightness and mechanical reliability for the reasons mentioned above.
また、パイプ嵌合法では、一定の長さの金属管に芯材を
挿入するので、芯材が金属管に引掛かり、摩擦力により
芯材が動かせなくなると、金属管に芯材を挿入できなく
なる。そこでこれを防止するため芯材の直径より、かな
り大きい内径の金属管に芯材を挿入しなければならなか
った。このため金属管の径を小さくするために金属管に
絞り加工を施す必要があった。In addition, in the pipe fitting method, the core material is inserted into a metal tube of a certain length, so if the core material gets caught on the metal tube and becomes immovable due to frictional force, the core material cannot be inserted into the metal tube. . In order to prevent this, the core material had to be inserted into a metal tube with an inner diameter considerably larger than the diameter of the core material. For this reason, it was necessary to draw the metal tube in order to reduce its diameter.
ところが、この金属管を縮径のため絞り加工をする際に
は金属管に大きな力が加えられた。そしてその力が芯材
に伝わり、芯材を損傷することがあった。However, when drawing this metal tube to reduce its diameter, a large force was applied to the metal tube. The force was then transmitted to the core material, sometimes damaging the core material.
さらに、押出法では一定量の金属を押出して金属管にす
るので金属管の長さに制限が生じ、金属管と金属管との
継目に溶接を施す必要があった。Furthermore, in the extrusion method, a certain amount of metal is extruded to form a metal tube, so there is a limit to the length of the metal tube, and it is necessary to weld the joints between the metal tubes.
この溶接した継目は、前述のような問題点を有していた
。This welded seam had the problems described above.
また押出法では金属を押出す圧力が芯材に伝わり、芯材
を傷めてしまうことがあった。In addition, in the extrusion method, the pressure to extrude the metal is transmitted to the core material, which may damage the core material.
また、押出法では鉛等の軟らかい金属でないと、細径に
押出して金属管にできないので、高強度の金属管を芯材
に被覆することができなかった。In addition, in the extrusion method, a metal tube cannot be made by extruding a soft metal such as lead into a small diameter, so it has not been possible to coat a high-strength metal tube with a core material.
したがってこの発明は上記のような問題点を解消するた
めなされたもので、金属製被覆材にピンホール等の欠陥
が発生せず、かつ金属製被覆材の長尺化が図られ、かつ
芯材が圧力等で傷まず、かつ芯材に高強度の金属を被覆
できる、芯材を金属被覆する方法を提供することである
。Therefore, this invention was made to solve the above-mentioned problems, and it is possible to prevent defects such as pinholes from occurring in the metal sheathing material, to increase the length of the metal sheathing material, and to improve the length of the metal sheathing material. It is an object of the present invention to provide a method for coating a core material with a metal, in which the core material is not damaged by pressure or the like, and the core material can be coated with a high-strength metal.
［課題を解決するための手段］
この発明の芯材を金属被覆する方法は、溶融金属を入れ
る容器に設けられた貫通孔の一方側から他方側へ芯材を
通す工程と、
該貫通孔の他方側周囲に設けられた環状孔で、該溶融金
属を鋳造して作製した被覆材を、該貫通孔の他方側から
出てきた芯材に被せる工程とによって芯材に金属被覆を
する。[Means for Solving the Problems] The method of metal coating a core material of the present invention includes the steps of passing the core material from one side to the other side of a through hole provided in a container containing molten metal, and The core material is coated with metal by a step of covering the core material coming out from the other side of the through hole with a covering material produced by casting the molten metal through an annular hole provided around the other side.
なお、この発明は、好ましくは該芯材と該貫通孔の間に
断熱部材を設けて行なう。Note that, in the present invention, a heat insulating member is preferably provided between the core material and the through hole.
また、この発明の芯材を金属被覆する方法においては、
該金属被覆工程に引き続き、該被覆材の縮径加工を行な
うことができる。Furthermore, in the method of metal coating the core material of the present invention,
Following the metal coating step, the coating material can be subjected to diameter reduction processing.
また、この発明においては、該被覆材の鋳造を、該溶融
金属が該環状孔から該容器の外へ出ると同時に冷却して
凝固して鋳造することが好ましい。Further, in the present invention, it is preferable that the coating material is cast by cooling and solidifying the molten metal at the same time as it exits the container from the annular hole.
また、該溶融金属は、一方向的に凝固することが好まし
い。Moreover, it is preferable that the molten metal solidify unidirectionally.
［作用］
この発明の方法においては、金属を容器に供給しながら
、貫通孔の他方側周囲にある環状孔で鋳造される被覆材
を、貫通孔の一方側から他方側へ通され′る芯材に被覆
していくので、金属を被覆してなる製品の長尺化が図れ
る。[Operation] In the method of the present invention, while supplying metal to the container, the coating material cast in the annular hole around the other side of the through hole is coated with a core that is passed from one side of the through hole to the other side. Since the material is coated with metal, it is possible to lengthen the length of the product made by coating the metal.
またこの発明の方法においては、上記理由により被覆材
を長尺化でき、かつ溶融金属を鋳造して被覆材を形成す
るので、被覆材にピンホールが発生しない。Further, in the method of the present invention, the covering material can be made long for the above-mentioned reasons, and since the covering material is formed by casting molten metal, no pinholes are generated in the covering material.
またこの発明の方法においては、被覆材を芯材の周囲で
鋳造し、またこの被覆材を芯材の移動方向と同じ方向に
移動させて芯材に被覆するので、芯材が被覆材に引掛か
るといったことが発生しにくい。このためパイプ嵌合法
のように芯材の挿入に問題を生じにくい。Furthermore, in the method of the present invention, the covering material is cast around the core material, and the covering material is moved in the same direction as the moving direction of the core material to cover the core material, so that the core material is attracted to the covering material. It is unlikely that this will occur. Therefore, unlike the pipe fitting method, problems with inserting the core material are less likely to occur.
またこの発明の方法においては、溶融金属を鋳造して被
覆材にし、それを芯材に被覆していくので高強度の金属
を心材に被覆できる。なぜならば高強度の金属であって
も溶融状態なら容易に被覆材に鋳造できるからである。Furthermore, in the method of the present invention, the molten metal is cast into a coating material and the core material is coated with it, so that the core material can be coated with a high-strength metal. This is because even high-strength metals can be easily cast into coating materials if they are in a molten state.
また、この発明の方法においては、押出法のように固体
状態の金属を塑性加工して被覆材にするのではなく、溶
融金属を鋳造して被覆材にするので、被覆材を作製する
のに多大の圧力を要しない。Furthermore, in the method of the present invention, the molten metal is cast into the cladding material, rather than the solid metal being plastically worked into the cladding material as in the extrusion method. Does not require a lot of pressure.
このため装置面でも小、型化が可能であるし、また被覆
材を作製する際に加えられる力が芯材に伝わり、芯材を
傷めてしまうということはない。Therefore, the device can be made smaller and more compact, and the force applied when producing the covering material will not be transmitted to the core material and damage the core material.

頼性が高まる。[Effects of the Invention] As explained above, in this invention, while supplying metal to the container, the coating material cast in the annular hole around the other side of the through hole is transferred from one side of the through hole to the other side. Since the core material that is passed through is coated, the length of the covering material that covers the core material can be increased. Therefore, there is no need to weld the joint between the covering materials. The reliability of the welded seam is therefore increased.
また、溶融金属を鋳造して被覆材にするので被覆材自体
にもピンホールが発生しない。Furthermore, since the coating material is made by casting molten metal, pinholes do not occur in the coating material itself.
また、芯材の周囲で鋳造した波田村を芯材の移動方向と
同じ方向に移動させて、芯材に被覆するので芯材が被覆
材に引掛かっても被覆材を芯材に被覆していくことがで
きる。このためパイプ嵌合法における単尺より長尺に加
工することができる。In addition, the Hatamura cast around the core material is moved in the same direction as the movement of the core material to cover the core material, so even if the core material gets caught in the covering material, the covering material will still cover the core material. be able to. Therefore, it can be processed into a longer length than a single length in the pipe fitting method.
また、溶融金属を鋳造して被覆材にし、芯材に被覆して
いくので、高強度の金属を芯材に被覆できる。Furthermore, since the molten metal is cast to form a coating material and the core material is coated, the core material can be coated with a high-strength metal.
また溶融金属を被覆材に鋳造するには力を要しないので
、被覆材を作製する際に加える力が芯材に伝わり芯材を
傷めてしまうということはなくなる。Furthermore, since no force is required to cast the molten metal into the covering material, there is no possibility that the force applied when producing the covering material will be transmitted to the core material and damage the core material.
